Simulate pressing a Flic button in the iOS app

Change the app so that you can click on buttons that are configured under the hub as if they were the real physical button and perform the correlating action e.g. virtual button via phone.
Could even make them work over internet, which would allow remote execution.

Found today that you can make widgets for the phone buttons. So this proves it’s possibel to have a virtual button. If this could be expanded out to allow widgets for the hub and allow buttons in app to be functional like virtual buttons.
